Ariens Company has learned that th e engine pull ey (p/n 07331 600) and crank shaft spacer (p/ n 04519200) us ed on the
Pro-Turn mode ls in the seria l number ranges li sted abo ve may not be clam ped tightly when the clutch is mounted. Th is
possible condition is due to variances in the length of the engine crankshaft and the components mounted on the
crankshaft.

To eliminate this condition, Ariens has created a clutch spacer kit p/n 59102100. This kit contains a new crankshaft
spacer (p/n 04519200) and a new clutch mounting bolt (p/n 05900043). See Figure 1.

The new spacer is slightly longer than the original to ensure that the clutch, spacer, and engine pulley are clamped
tightly when properl y mou nted on the cr anksh aft. The new sp ac er is gold in co lor so it c an be easily dist inguishe d

from the original spacer which is black.

The new clutch-mounting hex bolt is ¼" longer than the original to ensure adequate thread engagement.

updated with kit 59102100 if necessary.
